SF300-48P-K9-UK is a Cisco Small Business 300 managed access switch with 48 fixed 10/100 copper ports, including 48 802.3af PoE outputs sharing 375W, plus two dedicated Gigabit copper and two copper/SFP combo 1G uplinks. The full-width 1U enclosure fits a small business access rack with an internal AC supply. Each combo position accepts a copper or fiber connection, with only one side active at a time. Static inter-VLAN routing gives the platform a Layer 2+ role without an enterprise license tier. The SF300-48P configuration serves existing Fast Ethernet wiring while allowing a Gigabit distribution handoff. Endpoint power must be planned against the shared allocation rather than multiplied by the individual port ceiling. The fixed uplink layout requires no network module purchase.

17.6 Gbps switching capacity is the model's published fabric figure, and 13.1 Mpps forwarding measures its small-packet rate. SF300-48P-K9-UK has 128 MB of CPU memory, 16 MB of flash, and an aggregate packet buffer shared across active ports. The web interface, SSH or Telnet CLI, SNMP, VLAN configuration, STP/RSTP/MSTP, and LACP support day-to-day managed operation. Static IPv4 routing can connect configured VLANs; dynamic enterprise routing protocols are outside this platform role. Both copper/SFP combo uplinks accept documented MGBSX1 or MGBLX1 1G optics, with each optical interface sharing a logical position with its paired copper port. 3 fixed fans cool the enclosure, so fan status is part of hardware checks. An internal universal AC supply powers the unit. Hardware stacking and a redundant internal supply bay are absent.
ORM Systems offers SF300-48P-K9-UK new sealed or certified refurbished and accepts purchase orders for either condition. Certified refurbished managed units are inspected and bench-tested, firmware verified, and wiped to factory default; every port is checked for a link at rated speed. PoE output is verified under load on each powered port. Confirm the Cisco ordering PID SRW248G4P-K9-UK, regional power connection, and any required MGBSX1 or MGBLX1 optics before releasing the PO. New stock has up to a 3-year extended ORM warranty, refurbished stock up to 1 year, and every condition has 30-day returns subject to terms. Volume orders may use PO acceptance, Net-30 for government, UK/EU/US/MEA stock, and RMA with advance replacement.

A site maintains 48 Fast Ethernet endpoint links and needs a compatible managed switch for an existing Small Business 300 configuration. SF300-48P-K9-UK provides two dedicated Gigabit copper and two copper/SFP combo uplinks without a removable network module. Record the port plan, saved VLAN configuration, regional power connection, and chassis label before the purchase order.
A branch is adding phones, cameras, or access points to an established rack. SF300-48P-K9-UK supplies PoE on 48 10/100 ports, with 375W shared across the chassis. Total the connected device loads and confirm that each selected port is powered before the PO; the full per-port maximum is not available simultaneously.
A multi-site small business keeps a spare for SF300-48P deployments after the 300 Series retirement. SF300-48P-K9-UK uses the Cisco order number SRW248G4P-K9-UK for UK region. Confirm the chassis label, boot state, matching configuration, mounting hardware, and required power connection before the purchase order is released.
Ten gigabit distribution uplinks
SF300-48P has 1G copper/SFP uplinks and no built-in 10G port. Choose a currently supported switch with documented 10G uplinks when the distribution requirement is 10G.
Hardware stack as one chassis
SF300-48P has no dedicated hardware stacking capability. Specify a currently supported stackable switch where a single control plane across multiple chassis is required.
Active Cisco service coverage
Cisco places the Small Business 300 family among retired switches. Select a currently supported Cisco platform when vendor maintenance or security updates are mandatory.
Gigabit speed at access ports
The 48 fixed access ports operate at 10/100, while the uplinks are 1G. Select a current Gigabit access switch if endpoints require 1G.

SF300-48P-K9-UK identifies the Cisco SF300-48P managed Fast Ethernet switch with 48 copper access ports. Cisco's regional ordering PID is SRW248G4P-K9-UK; the catalog model spelling and ordering PID should be matched before purchase. The UK regional form concerns the sales and power connection, not a different Ethernet port layout.
SF300-48P-K9-UK uses the Small Business 300 web user interface and command-line access over SSH or Telnet. SNMP monitoring, VLAN settings, and saved configurations are available on the managed platform. Keep a backup of the installed configuration and verify the software image before introducing a replacement unit.
SF300-48P-K9-UK belongs to Cisco's retired Small Business 300 switch family. Cisco no longer supports products in that retired category. An installed unit can remain a replacement target, but purchasing should account for firmware availability, a tested spare, and an independent RMA path rather than assuming new Cisco service.
SF300-48P-K9-UK is available from ORM Systems new sealed or certified refurbished. ORM Systems offers new sealed stock with up to a 3-year extended warranty or certified refurbished stock with up to 1 year; both carry 30-day returns subject to terms. Cisco lists the 300 Series as retired, so Cisco service and the original limited lifetime hardware coverage have ended.
SF300-48P-K9-UK supplies 802.3af PoE on 48 access ports with a shared 375W allocation. A powered port can deliver up to 15.4W until the common budget is exhausted. Record every device's demand and check the total before assigning ports; the chassis budget is not a per-port guarantee.
SF300-48P-K9-UK has two 1G RJ-45/SFP combo positions. Each logical uplink can operate over copper or an installed SFP optic, with the unused medium inactive. MGBSX1 is a supported multimode option and MGBLX1 is a supported single-mode option; select fiber type and optics before ordering.
SF300-48P-K9-UK supports static routing between VLANs as a Layer 2+ Small Business 300 switch. It does not require a Catalyst Network Essentials or Network Advantage license tier. Define the gateway interfaces and upstream route plan when moving a configuration from another switch, rather than treating management access as routing.
SF300-48P-K9-UK cannot join a true hardware stack because the 300 Series model has no dedicated stack facility. Its uplink ports are ordinary Ethernet interfaces, and managing multiple units does not create one stack control plane. Record a separate configuration, power feed, and spare-unit plan for each chassis.
SF300-48P-K9-UK supplies 48 fixed Fast Ethernet access ports and 4 logical 1G uplink positions. Access ports stop at 100 Mbps even though the uplinks reach 1G. No 10G uplink is built in. Match endpoints and distribution links to those published speed classes before purchase.
SF300-48P-K9-UK uses an internal AC supply with a 100–240V AC input. The published 465W worst-case draw includes the measured PoE load condition. There is no second internal hot-swappable PSU bay. Verify the included regional connection and available electrical capacity at the installation location.
